A rectangular prism has a length that is 3 inches shorter than the height and a width that is 5 inches longer than the height. F
LUCKY_DIMON [66]

An equation for the volume of the prism as a function of the height is Volume = h³ + 2h² - 15h.

  • We are given a rectangular prism.
  • A rectangular prism is no different than a cuboid.
  • Let the height of the rectangular prism be "h".
  • The length of the rectangular prism is "h-3".
  • The width of the rectangular prism is "h+5".
  • The volume of the rectangular prism is the same as that of the cuboid.
  • The volume of the rectangular prism is the product of its length, its width, and its height.
  • The volume of the rectangular prism is (h - 3)*(h + 5)*h.
  • An equation for the volume of the prism as a function of the height is :
  • Volume = (h - 3)*(h + 5)*h
  • Volume = (h² + 2h - 15)*h
  • Volume = h³ + 2h² - 15h

What best describes the expression y over 7? 7 times some number Some number minus 7 7 more than some number Some number divided
marysya [2.9K]
"Over" usually means divide. First hint, check.

If we write it out, it looks like this:

\frac{y}{7}

This is the same as <em>some number divided by 7.</em>

2) An $80 text book was on sale for $49.60 at the used book store. By
nadya68 [22]

Answer:

38%

Step-by-step explanation:

Original price = $ 80

Price after reduction = $ 49.60

Reduction = 80 - 49.60  = $30.40

Percentage of decrease = \frac{reduction price}{original price}*100

                                         = \frac{30.40}{80}*100\\\\=\frac{3040}{80}

                                          =  38%
